.a. hopper in which the dough is pl'aced,-'a

spout leading from the hopper to an expressing chamber, a screw deviceinsaid chamber for forcing out the dough in tubular form, and a cutterfor cutting oif the rings of dough to form the doughnuts. The machine isso supported that it can be moved to various positions, above a fryingpan or tank, so that the doughnuts will be dropped at dilferent placestherein, as they are cut oil. In addition to the general features thusreferred to, the machine contains a number of improvements in thedetails, as will be more fully apparent from the following descriptionand the accompanying drawings.

in the drawings-" Figure 1 is a side elevation of the chine.

Fig. 3'is an end elevation of the machine. Fig. 4 is a bottom view withthe cutter in one position.

Fig.5 is a similar view with the cutter in another position. 7 Fig. 6 isa detail of a gear. Fig. 7 is a detail of a cam for operatin the cutter.

Fig. 9 is a detail of the screw.

Fig. 11 is a detail of the cutter.

Fig. 12 is a horizontal section through the expressing cylinder andassociated parts.

Fig. 13 is a detail of the device for oscillating the cutter.

Fig. 14 is a top view of the same.

Referring specifically to the drawings, 6 indicates a hopper mounted ona chute 7 which leads into the expressing cylinder 8. The hopper isremovable, for cleaning or other purposes, and its lower end fits in thetop of the chute 7 where it is held by pins 9 and a catch 10. Themachine is supported on tracks or arms 11, the chute having side flanges1.2 which confine it to the tracks, and it may be slid back and forth onthe tracks by means of a handle 13 at the front. The tracksll aresupported by a post 14, being pi-voted to brackets thereon asindicatedat 15, so that it may be swung around horizontally to differentpositions as shown in dotted lines in Fig. 2. By these means the machinemay be moved either sidewise or in and out so as to drop the doughnutsat different places in a pan of hot grease, for example, (not shown)placed to; receive the same. This is convenient for rapid operation ofthe machine.

The cylinder 8 contains a screw or worm consisting of an arbor or shaft16 and the spiral blades 17, and the outer edge of the upper part, atleast, of each blade is bent down or over as indicated at 18, forming abead which acts to gather the dough from the chute 7 and draw it intothe cylinder. 1 have found this much more satisfactory than a plain fiatblade whichpermits the dough to slip or not feed into the cylinder. Theupper end of the screw shaft has an axial stud 19 with a cross pin 20adapted toengage in a slot 21 in a pinion 22 which turns in a bearing.23 in the top of the cylinder, and this pinion meshes with a bevelpinion 24 on a shaft 25 which is carried in bearings 26 on the side ofthe chute and is turned by a crank 27 at the end thereof.

To govern the amount of dough pressed out by the screw I employ asegment plate 28 (see Figs. 8 and 10). This plate is secured on athreaded axial stud 29 at the lower end of the shaft 16, by means of anut 30, and the plate 28, by loosening the nut,

can be turned to varythe size of the discharge spaces at the lower endof the screw, and thus vary the size or thickness of the strip of doughpressed out by the screw.

In the lower end or mouth of the cylinder 8 is a circular contractedmouthpiece or ring 31, held in position by lugs 32 which engage pins 33on the outside of the cylinder 8, and at the center of this mouthpieceis a tapering core 34 which forms the hole in the doughnuts. This core34 is supported by a pair of cross pins 35 which are located so farabove the lower end of the mouthpiece that the dough, although dividedby the pins, will unite again before it reaches the discharge.

so that it can be renewed it broken. shafnh e2 pinned as indmatecl at esto the stroke.

The mouthpiece is contracted and the core is slightly expanded, towarclthe tlischetge opening, so hat the slough is coinpressetl into a solidtube as it is (lischargecl, The core E l also supports the screw, whichsests thereon, so the screw can he dropped out cleaning, by removing themouthpiece, the cross pin disengaging from the slot 21,. I

For cutting oh the doughnuts, as the dough is expressed "from thecylinder, it einploy a. howecl frame i0 with a Wire or hleele llstretched across the same. The frame is held in-e shenli e2 (Fig. ll) hyscrew 43, This towel encl oi a me; shalt which is supported by bracketsQ6 and $7 on the sicle oi the cylinder, The upper end of this rock shaftis orah-heel as indicated at 4:0 fiIOUIlCl the shaft 25, and carries apair of Wipers e9 projecting at an angle to each other anti adapted tohe engaged intermittently by acam 50 on the tlish 51 secured to thechive 25, By reason of the locetion of the Wipers the stroke oi thec'uttei' is quick in each direction, with e dwell between each As thedrive shaft is rotated the cam 50 strikes first one Wiper and then theother and techs the shaft l l accortlingly, and this swings the cutter:lfrarne and carries the cutter ll hack and forth across the mouthpiece,at each time cutting 03% a ring of the slough. Stops 5:2 limit the swingof the trains, these steps depending from the hteclzet il". Thedifferent positions of the cutter are sho n in Figs. ontl 5, I

For closing the mouth of. the cylinder, as

when the machine is n I use, I ipnovicle a swinging shield 53 PlYUtBiil5% to the l and ei'rangetl to swing erountl 3 lie inoutnniece, d ofclosure e t-en he pivot pin of his i linecl uncle? a Washer 57 on thepivot, en the spring acts to holcl the shield tightly egeinst themouthpiece. W hen the shield is swung around to closed position thespring Willyield slightly to permit the shielrl to pass up the taperancl under the mouthpiece, ancl acts to holtl the same in close contacttherewith until it is opened. W hen the machine is statted the frame 40will strike the shield and lil'lOClZ it open, 57 is a shield fastened tothe cylinder 8 and located under the crank 52? to prevent the hancl ofthe operator being burnt by grease splashing up from a pan into whichthe doughnuts are dropped.

In use the dough is placed in the hopper, and hy turnin the crank it isfed in a ring through the mouthpiece and cut off into doughnuts, and asstated above the machine can he shifted in and. out on the tracks 11, O1swung to the right 01 the left, to drop the doughnuts at cliiierentplaces.

l claim:

1. lhe combination with a dough-cutting and dropning machine, of a rigidswinging support on which the machine is slidahly mounted, to permit thecuttings to he dropped at olifierent places,

2. The combination with a dough-cutting antl dropping machine, of atrack on which the machine is sliclahly mounted, to drop the cuttings atclifi erent places, saitl track being pivotecl at one end thereof, toswing horizontally.

3. The'conibination With a dough-cutting and dropping machine, of aswinging track comprising a pair of rigid bars between "which themachine is mounted, and a single pivotal support for saicl bars.
